I need a small quantity of 27.12MHz crystal oscillators in the DIP
14/4 pin can package. The usual places (digikey, mouser) don't carry
that frequency. Anyone know a place that will sell me <10 for a
reasonable price?
It always helps to say what you need it for, since after all it may
turn out that you can use some other freuqency, or some other solution.
Use various multipliers to see if it lands on a common oscillator frequency.
then you just need to divide it down. Even multiples make the divider
easy.
Have one made. That will cost, but if you actually really need that
frequency there may be no choice. A custom crystal may be somewhat
cheaper.
27.125 is/was a common CB frequency, Channel 14 I think. Before
synthesizers took over, many CB sets and most 100mW walkie talkies
used such a frequency in the transmitter, though it was usually an
overtone crystal.
But until you reveal what you need it for, we won't know whether it
really needs to be at 27.125MHz or you merely think it does.
